[rt-users] Ticket could not be created due to an internal error

[Jason Brown]

I recently had a server crash and I am reinstalling RT from scratch, the 
version that was installed was 3.6.7.  I installed that version on the 
new server and reimported the MySQL database, then upgraded RT to 3.8.8. 
  Everything seems to be working properly, I am able to login, create 
and resolve tickets through the web GUI, however if I try to send an 
email to the designated email address to create a ticket I receive a 
bounce back email message stating "Ticket could not be created due to an 
internal error."

I do not see anything in the logs that would indicate errors.  When the 
server does recieve a message, this entry is created:
  to=<rt at rt.millbrookprinting.com>, relay=local, delay=0.39, 
delays=0.02/0.01/0/0.36, dsn=2.0.0, status=sent (delivered to command: 
/opt/rt3/bin/rt-mailgate --queue Incoming --action correspond --url 
http://rt.millbrookprinting.com/)

The server is running:
CentOS 5.5 (SELinux is disabled)
Postfix
MySQL
Apache

Thanks
